Berryman Products 0117 B-12 Chemtool Carburetor, Choke and Throttle Body Cleaner [Not VOC Compliant in Some States], 16-Ounce (117) (Pack of 2)

B -12 is a chemical heavyweight. You can watch varnished fuel and oil just (poof). It smells good, but also like death at the same time, and absolutely do not let it touch you. This stuff is real, and will tear you up with prolonged skin contact. Cleaned up baked on Chrysler Big Block oil leaks in seconds, stuff that had been on there for literal years. Carburetors, throttle bodies, just cleaning up the crap off your working it just dominates. It's a very good product, and worth the money.

Berrymans' B-12 is the vitamin shot your body needs as you age. It's easy to use—just add it to your tank before a fill-up, and it will keep your carb clean and running good as new. It's a great value and worth the investment to keep your car speeding along.

When your down to a quarter of a tank of gas dump this in and then fill up with super gas. Take a long ride on the highway and your entire fuel system will get cleaned. This B12 really works ! On my older vehicles I pour it directly down the carburetor to clean intake valves. Have been using this for years and have had no problems

Like all Berryman products they are the best

I haven’t found anything close to Berryman for carburetor cleaning. This is a FAR superior product.

This is great

I have used Berryman cleaner in the past. This does not seem as strong as it used to be. It still cleans but takes longer and more solvent is needed.

Both cans had pinholes in them that imperceptibly leaked until it was left on a shelf long enough to fill the room with fumes.
